Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a high-precision single-strand cable insulation stripping device. Background Technology

[0002] Cable insulation stripping devices are important tools used in fields such as power and communications. Their function is to strip the insulation layer of a cable from the conductor so that it can be installed, maintained, or recycled.

[0003] Existing cable insulation stripping devices experience wear on their cutters during operation due to continuous friction with the cable insulation, the influence of chemical components, and mechanical stress. This wear alters the blade shape, affecting the control of cutting depth and width, and reducing stripping accuracy. Insufficient accuracy may result in unsatisfactory insulation stripping lengths or even damage to the internal conductors, impacting cable performance and safety. Utility Model Content

[0004] This utility model provides a high-precision single-strand cable insulation stripping device, including a bracket, a rotating shaft, a protective shell, a motor, a knife holder, and two stripping blades. The two ends of the rotating shaft are rotatably connected to the left and right sides of the bracket, respectively. The protective shell is fixedly installed on the right side of the bracket. The motor is fixedly installed inside the protective shell, and the drive end of the motor is fixedly connected to one end of the rotating shaft. The knife holder is fixedly mounted on the rotating shaft. The two stripping blades are fixedly installed on the top and bottom of the knife holder, respectively, and the two stripping blades are arranged symmetrically from top to bottom. A detection unit is provided on the bracket.

[0005] Preferably, the detection unit includes an electric telescopic rod, a support box, a spring, a slider, a connecting rod, a contact head, and a pressure sensor. The electric telescopic rod is fixedly installed on the top of the support frame, and the driving end of the electric telescopic rod extends through the top of the support frame. The support box is fixedly installed on the driving end of the electric telescopic rod. The spring is located inside the support box, and one end of the spring is fixedly connected to the top of the support box. The slider is fixedly installed on the other end of the spring, and the slider is slidably connected to the inner wall of the support box. One end of the connecting rod is fixedly connected to the bottom of the slider, and the connecting rod extends through the bottom of the support box. The contact head is fixedly installed on the other end of the connecting rod. The pressure sensor is fixedly installed on the top of the support box, and the pressure sensor is located inside the spring.

[0006] Preferably, the contact head has an arc-shaped structure.

[0007] Preferably, the rotating shaft and the bracket are connected by a bearing, the inner ring of the bearing is interference-fitted with the rotating shaft, and the outer ring of the bearing is fixedly connected to the bracket. This invention provides a high-precision single-strand cable insulation stripping device, which, compared with existing technologies, offers the following improvements and advantages: By periodically or according to preset conditions, the two blades are automatically swapped, allowing them to alternate as the primary working surfaces. This effectively balances the wear on both sides of the blades, preventing premature failure due to excessive wear on one side, thus significantly extending the overall blade assembly's lifespan and reducing the frequency of blade replacement and maintenance costs. Simultaneously, the integrated detection unit can automatically detect the blade wear status in real-time or periodically. Through feedback information from pressure sensors, it can accurately determine the remaining effective working time of the blades and whether replacement is necessary. This not only improves the accuracy and efficiency of detection, avoiding subjective errors and omissions that may occur with manual inspection, but also provides operators with clear maintenance guidelines, ensuring continuous high-precision stripping operations and preventing problems such as decreased stripping accuracy and cable conductor damage caused by blade wear. Ultimately, this guarantees the quality of cable processing and the safe and stable operation of the power system. Attached Figure Description

[0014] Please see Figure 1-3 This utility model provides a technical solution: a high-precision single-strand cable insulation stripping device, including a bracket 1, a rotating shaft 2, a protective shell 3, a motor 4, a knife holder 5, and two stripping knives 6. The two ends of the rotating shaft 2 are rotatably connected to the left and right sides of the bracket 1, respectively. The protective shell 3 is fixedly installed on the right side of the bracket 1. The motor 4 is fixedly installed inside the protective shell 3, and the drive end of the motor 4 is fixedly connected to one end of the rotating shaft 2. The knife holder 5 is fixedly mounted on the rotating shaft 2. The two stripping knives 6 are fixedly installed on the top and bottom of the knife holder 5, respectively, and the two stripping knives 6 are arranged symmetrically up and down. A detection unit 7 is provided on the bracket 1.

[0015] Specifically, the detection unit 7 includes an electric telescopic rod 71, a support box 72, a spring 73, a slider 74, a connecting rod 77, a contact head 75, and a pressure sensor 76. The electric telescopic rod 71 is fixedly installed on the top of the bracket 1, and the driving end of the electric telescopic rod 71 extends through the top of the bracket 1. The support box 72 is fixedly installed on the driving end of the electric telescopic rod 71. The spring 73 is located inside the support box 72, and one end of the spring 73 is fixedly connected to the top of the support box 72. The slider 74 is fixedly installed on the other end of the spring 73, and the slider 74 is slidably connected to the inner wall of the support box 72. One end of the connecting rod 77 is fixedly connected to the bottom of the slider 74, and the connecting rod 77 extends through the bottom of the support box 72. The contact head 75 is fixedly installed on the other end of the connecting rod 77. The pressure sensor 76 is fixedly installed on the top of the support box 72, and the pressure sensor 76 is located inside the spring 73.

[0016] Specifically, the contact head 75 has an arc-shaped structure.

[0017] Specifically, the rotating shaft 2 and the bracket 1 are connected by a bearing. The inner ring of the bearing is interference-fitted with the rotating shaft 2, and the outer ring of the bearing is fixedly connected to the bracket 1.

[0018] Working principle: Motor 4 drives shaft 2 to rotate, and shaft 2 drives two symmetrically arranged stripping blades 6 to rotate synchronously through the blade holder 5 fixedly mounted on it. Normally, the lower stripping blade 6 undertakes the main cutting work, responsible for stripping the insulation layer of the cable, while the upper stripping blade 6 is in standby mode. To even out wear, motor 4 periodically executes a rotation program, causing the blade holder 5 to drive the two stripping blades 6 to exchange positions, that is, the lower main working blade moves to the upper standby position, and the upper standby blade moves to the lower main working position. After each exchange of stripping blades 6, the electric telescopic rod 71 fixed to the top of bracket 1 will be activated, extending downwards, driving the support box 72 fixed at its drive end and the arc-shaped contact head 75 at the end of the connecting rod 77 inside the box to descend together, moving to the designated detection position on the top of the stripping blade 6 that was just used and is now in the upper standby position. When the arc-shaped contact head 75 contacts the tip of the peeling blade 6, if the wear of the peeling blade 6 is within the normal range, the cutting edge remains intact, and its tip still has sufficient protrusion height and contact area, the contact head 75 will press against the tip of the peeling blade 6. This pressure will be transmitted to the slider 74 through the connecting rod 77, overcoming the preload of the spring 73 and pushing the slider 74 to slide upward within the support box 72, thereby actuating the pressure sensor 76 located at the top of the support box 72. The pressure signal sensed by the pressure sensor 76 will be collected and processed to determine the current state of the peeling blade 6. If the pressure value reaches the preset normal range, it indicates that the peeling blade 6 is only slightly worn and can still be used as a spare or as the main working blade after the next swap. Conversely, if the peeling blade 6 is severely worn, the tip becomes blunt, or the height is reduced too much, the contact head 75 cannot effectively press against the peeling blade 6 and push the slider 74 to actuate the pressure sensor 76, or the generated pressure signal is far below the normal threshold, the system will determine that the peeling blade 6 has reached its wear limit and needs to be replaced. Through this automatic switching and subsequent automatic detection mechanism, the wear status of the stripping blade 6 is monitored and managed.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
